Abstract

A mobile terminal with multi-antenna (200) based on CDMA, comprises a plurality of groups of radio frequency signal processing modules (202), for transforming received multi-channel radio frequency signals based on CDMA to multi-channel baseband signals; a multi-antenna module (206), for combining said multi-channel baseband signals output from the plurality of groups of radio frequency signal processing modules into single-channel baseband signals according to control information received one-off when said multi-antenna module enables a multi-antenna baseband processing; and a baseband processing module (203), for providing said control information to said multi-antenna module and baseband processing said single-channel baseband signals outputted from said multi-antenna module.
